The SavedModel format is the default model serialization and deserialization format used by TensorFlow. In layman's terms, this can be understood as a container that holds everything there is to reproduce a model from scratch elsewhere without access to the original code that created it. We can use SavedModel to transfer trained models from the training to the inference phase or even to transfer state between different parts of the training process. In a nutshell, it can be said that SavedModel contains a complete TensorFlow program along with model weights and descriptions of the various compute operations described. While working with the Python API of TF 2.0, it is now possible to export certain native Python operations along with the model. This is facilitated largely by the tf.function and tf.autograph APIs. In the...

Overview of this book
TensorFlow is an end-to-end machine learning platform for experts as well as beginners, and its new version, TensorFlow 2.0 (TF 2.0), improves its simplicity and ease of use. This book will help you understand and utilize the latest TensorFlow features.
What's New in TensorFlow 2.0 starts by focusing on advanced concepts such as the new TensorFlow Keras APIs, eager execution, and efficient distribution strategies that help you to run your machine learning models on multiple GPUs and TPUs. The book then takes you through the process of building data ingestion and training pipelines, and it provides recommendations and best practices for feeding data to models created using the new tf.keras API. You'll explore the process of building an inference pipeline using TF Serving and other multi-platform deployments before moving on to explore the newly released AIY, which is essentially do-it-yourself AI. This book delves into the core APIs to help you build unified convolutional and recurrent layers and use TensorBoard to visualize deep learning models using what-if analysis.
By the end of the book, you'll have learned about compatibility between TF 2.0 and TF 1.x and be able to migrate to TF 2.0 smoothly.
